In the particularly difficult question of global
warming, thus far most economists have argued that it will be more efficient to respond to the problems
caused by global
warming as they occur than to make serious efforts to reduce it, since these efforts would

slower warming, but can nevertheless contribute to ocean acidification.
In the case of
warming caused by a disproportionate increase in atmospheric CO2 (compared with oceanic CO2), an increase in temperatures only
slows down the rate at which CO2 is absorbed by the oceans.

Or are they missing natural influences that can
cause wide swings in ice and temperature, thereby dwarfing the
slow background
warming?
Simple physics dictates that with less sea ice there is magnified
warming of the Arctic due to powerful albedo feedback; this in turn reduces the equator to pole temperature gradient which
slows the jet stream winds
causing them to become more meridional; this combined with 4 % more water vapor in the atmosphere (compared to 3 decades ago) is leading to much more extremes in weather.
I do indeed presume that the rapid
warming of the Arctic is already affecting the Jet Stream, and thereby affecting the Northern Hemisphere's weather, and that continued rapid
warming of the Arctic will
cause the Jet Stream to
slow and weaken to the point of collapse, possibly in the not - too - distant future.

causes of
slowed surface air
warming is of course ongoing.
As it does so, it oxidises to CO2, dissolving in seawater or reaching the atmosphere as CO2 which
causes far
slower warming, but can nevertheless contribute to ocean acidification.
-LRB-- NAO) This sea ice then melts in the Sub Polar Atlantic, releasing fresh water into the sub - polar Atlantic waters, which in turn impedes the formation of NADW, which
slows down the thermohaline circulation
causing warm air not to be brought up from the lower latitudes as far north as previous while in lessening amounts.
A new study published in Nature Climate Change found that by taking into account the short - term changes
caused by factors like El Niño and La Niña cycles, they could accurately forecast the
slowed warming at the surface several years in advance.
My opinion expressed elsewhere is that almost all the temperature changes we observe over periods of less than a century are
caused by cyclical changes in the rate of energy emission from the oceans with the solar effect only providing a
slow background trend of
warming or cooling for several centuries at a time.
Some conference speakers decried Trump's move to withdraw the United States from the Paris climate accord, saying the international agreement to reduce carbon emissions offers the clearest road map for
slowing the global
warming that's
causing ice to melt and seas to rise.
The
slowed surface
warming is due in large part to changes in ocean cycles, particularly in the Pacific Ocean,
causing more efficient ocean heat uptake, thus leaving less heat to
warm surface temperatures.
What I am not clear on is what has changed in the last few years to
cause more heat to be captured by the oceans and less in the atmosphere with the resultant
slower rate of surface or atmospheric
warming.
And we also know that the correlation between global average temperature and atmospheric CO2 is statistically not very robust, so that something else must also «be at work» to
cause the gradual
warming (or «
slow thaw», as you've dubbed it).
However, the tide - gauge literature data shows the current, rather
slow but steady as opposed to accelerating, rate started in 1850, long before CO2
warming could have been the

caused (or can be
slowed) by human activity.
The orbital changes that
caused the ice ages are far too weak and
slow to
cause a

Several studies from this year show that the slowdown could be
caused by a natural cycle in the Atlantic or Pacific that

slowed or stopped global
warming now.
Wouldn't it be ironic if in the interest of global
warming we mandated massive switches to energy, which is a finite resource, which

There's mostly consensus on what's
causing global
warming (we are), as well as how quickly we need to work to
slow it down (very quickly).
The

Therefore, the enhanced ocean heat sink is the main
cause for the current
slowing in surface
warming.
A full reading of Tsonis and Swanson's research shows that internal variability from climate shifts merely
cause temporary
slow downs or speeding up of the long - term
warming trend.
To summarise the arguments presented so far concerning ice - loss in the arctic basin, at least four mechanisms must be recognised: (i) a momentum - induced
slowing of winter ice formation, (ii) upward heat - flux from anomalously
warm Atlantic water through the surface low ‐ salinity layer below the ice, (iii) wind patterns that
cause the export of anomalous amounts of drift ice through the Fram Straits and disperse pack - ice in the western basin and (iv) the anomalous flux of
warm Bering Sea water into the eastern Arctic of the mid 1990s.
If you believe, as I do, that radiative forcing tends to
cause global mean temperature increase, then it is a contradiction to believe that future rates of
warming will be higher when increases of radiative forcing are
slower than they were in the past.
Warmer seae were
